Tool recommendation for polishing polyester finishes ...?

[Vanderhoofven]

Greetings,

I am in the market for a electric polisher for the final step in polishing
out some scratches in a high gloss black polyester finish piano.  During
the PTG convention in July, 1999, in Kansas City, I attended a class taught
by Phil Glenn.  This hands on class  involved polishing out scratches in a
high gloss black polyester finish.  The final steps involved a handheld
electric polishing wheel with a soft buffing wheel and a bar of polishing
compound.

Today my quest for a handheld electric polishing tool took me to 6
different hardware/discount stores.  The only polishers for sale in most of
these places were designed for polishing car finishes.  Unfortunately, I
couldn't find what I was looking for.

Tool Requirements:
*Heavy Duty
*low RPMs (1000-1400)
*accepts 6" or 8" bench grinder polishing wheels

Does anyone know where such a tool can be purchased?

If not, does anyone have experience (good or bad) with using one of the
polishers designed for use on cars (the random orbiting polishers with a
lamb's wool bonnet).

Thanks for any and all responses!
